Northstar-at-Tahoe Resort in Lake Tahoe, CA, recently installed low-flow showerheads free of charge, in the 265 privately owned units that make up the resort’s lodging program. “As we replace older fixtures, we do so with more efficient, low-flow fixtures,” says Communications Manager Jessica VanPernis. “Additionally, all new construction projects are done following Title 24 guidelines [of the California Code of Regulations], which dictate the installation of low-flow products.”

According to the California Energy Commission Web site (www.energy.ca.gov), Title 24 sets “energy efficiency standards for residential and nonresidential buildings.” Title 24 was first established in 1978 as a way to create a legislative response to the need for California to reduce its energy consumption. Standards set by Title 24 are changed on a regular basis, with newest updates set to take effect July 2009. As a result of the new Title 24 amendments, ski resorts in the state now have legal incentive to consider better water conservation. In fact, the resorts in the US and Canada have already begun taking numerous steps to reduce water usage: installing low-flow fixtures, encouraging towel reuse, switching to waterless urinals, setting up efficient washing machines, and reducing water pressure.

And, ultimately, improving water efficiency just makes good business practice, says Geraldine Link, director of public policy for the National Ski Areas Association. “Water is a scarce resource, particularly in arid parts of the country,” she says.

Using snow gun increases the volume of snow created from any given amount of water.
Therefore, ski resorts are very open to finding ways to conserve water wherever possible. “There are a huge number of conservation measures in place at resorts with respect to snowmaking,” says Link. “Resorts implement a number of water conservation measures to make snowmaking highly efficient.”

Examples include:

  • Installing water coolers to lower the ambient temperature of the water and allow less water to be used
  • The use of efficient snow guns to increase the volume of snow produced from a given amount of water
  • Reducing the amount of water used in freestyle terrain by using dirt, rather than snow, in the construction of half pipes and other features
  • The installation of flow meters on snowmaking systems to accurately measure water usage
  • Actively monitoring leaks in the system
  • Using high-quality, reclaimed water for snowmaking

However, adds Link, it is important to keep in mind that water used for snowmaking is not considered a “consumptive” use of water. “Most of the water diverted from streams for snowmaking returns to the watershed,” she says. “Although it varies from region to region, a number of state studies show that approximately 80% of the water used for snowmaking returns to the watershed. Since the majority of water is purchased by the ski area and brought onsite through diversions, snowmaking actually benefits the watershed in which it is taking place and can help counteract the harmful effects of global warming.”

At Solitude Mountain Resort in Utah, Marketing Coordinator Nick Como says that using water-saving equipment in the snowmaking process is very important. Inside the Solitude Mountain’s new lodge, for example, automatic faucets were installed. But it’s outside where the resort really impacts its water usage.

“The snowmaking process, from start to finish, does everything possible to reduce water,” says Como. “The water is stored in underground mines, which nearly eliminates water vapor loss to the dry Wasatch air. Once the water is pumped through the system, Solitude uses the industry’s most efficient snow gun. The results are minimal evaporative loss and better snow.”

And, he adds, unlike snowmaking practices at other resorts, no additives are added to the water; therefore, once the snow melts and returns to the watershed, the water remains in pure form. “Better water efficiency is important to our resort, because every ounce of water saved is a potential snowflake in the making,” says Como. “Ski resorts can never have too much snow.”

The Aspen Skiing Company in Colorado recently switched to water efficient washing machines, replacing the old top-load machines in the Heatherbed Lodge with Maytag front-load washing machines. These machines don’t need to be completely filled with hot water, and they rotate clothes through two-thirds less water. Maytag estimates that, within one year, the new washers will pay for themselves, with savings on water, sewer, and energy costs. At the Aspen Skiing Company, a facility with 32 occupants can save 48,000 gallons of water annually with these new washing machines.

Keystone Resort has recently instituted a number of water-saving initiatives.
“We were buying new machines about seven years ago in an employee housing unit,” says Auden Schendler, executive director of sustainability for Aspen Skiing Company. “We bought four Neptune coin-operated front loaders. Then it became obvious that any time we bought new machine, we should buy horizontal axis machines.”

Better water efficiency is important to the resort, largely due to water availability. “We’re a values-based business,” he says. “Our guiding principles include a mandate to be responsible stewards of our environment.”

One of the obstacles faced in making the switch, at least at first, was some difficulty finding the machines, as they were relatively new, but that was easily overcome with a bit of research. According to Schendler, the upfront cost was also higher, but that was justified with the savings. The front-loading, horizontal-axis washer uses about half the water of a top-loader washer because, instead of agitating clothes in a tub, it circulates the clothes through water at the bottom of the basin. It also uses less detergent (more savings) and spins faster, so the clothes require less time in the dryer. Finally, the clothes last longer because they are dried less (drying can be rough on clothing). Schendler says that Aspen Skiing Company advertises to guests about its environmental work, but not necessarily with specific mention of the water-saving washers.

For other resorts thinking of new ways to save, he says it would be silly not to consider axis washers, given that these cost about the same as standard machines and have great payback. “Or, conversely, our competitors can choose not to use them, and we’re happy to capture the competitive advantage of being more efficient,” adds Schendler.

He goes on to say that, along with the new washers, a new restaurant called Sam’s Smokehouse, at Aspen’s Snowmass, is using low-flow and waterless features highlighted by waterless urinals in the restroom. “Those are the big savers,” says Schendler.

At Wintergreen Resort, in Wintergreen, VA, a snowmaking arsenal has been added this year, and the resort is combining automated fan guns into the current inventory of automated snowmaking equipment, according to Anne Marie Jones, public relations and communications manager. These fan guns, provided by Johnson Controls Snow, ride on the cutting edge of design in the snowmaking industry and will push us into the future with more snow, sooner.

“This new design uses less electricity and is more efficient at producing large amounts of snow, reducing our overall carbon footprint,” says Jones. “We can also run them earlier in the year to get a jump start on ski season, so that you can enjoy winter sports even more each year. These fan guns have the potential to increase our production, before the winter holidays, by 44%. For those of you that love tubing, we are using them there as well, so come and see just what our expert snowmakers can do with more new technology tied to our already-top-of-the-line automated snowmaking system.” Next Page >
